The hardware and software for a small stm32 based lab power supply

The control processor is a stm32f103c8t6, an Arm Cortex-M3 MCU with 64 Kbytes of flash memory and a 72 MHz CPU. The current code runs on libopencm3 and FreeRTOS. The display is a 256x128 OLED display. It is driven by uGui software. The unit is composed of two boards. The top board is the control and display board. The board below is the regulator board. The regulator board is composed of a low voltage drop linear regulator and a highly efficient switching regulator. Because of the combined efficiency of the switching and linear regulator not much of a heat sink is required. To reduce the…
